`int 1/x^2 (2x+1)^3`dx

Evaluate: int_1^3 1/(x^2(x+1))dx

Evaluate: int_1^3 1/(x^2(x+1))dx

5. int(1)/(3x^(2)+2x+1)dx

int (2x^2)/(x^3+1) dx

int (2x^2)/(x^3+1) dx

int 3^(2x+1) dx

int 1/(2x^2+3x+4) dx

IfI_1=int_0^1 2^(x^2)dx ,I_2=int_0^1 2^(x^3)dx ,I_3=int_1^2 2^(x^2)dx ,I_4=int_1^2 2^(x^3)dx , then which of the following is/are true?

Evaluate: int_1^2 1/((x+1)(x+2))dx (ii) int_1^2 1/(x(1+x^2))dx

int (x^6+2x^2+3x+1) dx
